My understanding of reservation policy and equal oppportunity policy

A representative sub population reflects the same probabilities as that exist in total population.This is the basis of random sampling procedure. If the sub population does not reflect the the same probabilities as hat exist intotal population, two things can be said .1 The sample is biased .
2. The issue under consideration in the sub population is not reflecting the same probability as in the total population because some thing is working as a preferential filter . The filter could be the government policy, or the social authority prejudice or preference.
To give an example :
Women are about 50% in total population. You do not see the same percentage
( Probability) in the elected institutions like assemblies and parliament .
It could be that women prefer to be home makers or men like to have the real power in their hands. It is deither a prefernce or a social suppression
Similarly, in the profession prostitution , you do not see 50% men.Here we can social mind set acting as filter . Similarlywomen of weaker sections constitute a large percentage . That means the conditional probability is high for weaker section women
In educational institutes and jobs we find that the Weaker sub populations are not in the same proportion as in total population.How to make it attain the same proportion?
The government policy is to make reservations
We do not have reservations in fields like sports and movies where skills are said to be important . Such skills are not felt important to study or administer.by our policy makers.
We lower skills level to make the sub populations tpo reflect population probabilities better
Is it desirable. ? Example.An unskilled doctor is avoided by all affording communities. Such unskilled doctors if he belongs to a weaker section or favoured group , is provided with a job and thrust on sub populations of weaker sections .to get their ailments treated .My opinion

All communities ( sub populationds) have their preferred vocations . For instance , the kodava men prefer to be soldiers or planters . The policy should be to make them succeed in those vocations. However if some people wish to do some thing different , they should give them equal opportunities. Provide them greater time for equipping themselves with the desired levels of skill.
This is my first attempt to express with time I may be able to express more sharply
